Hi,
On the basis of information provided by you ,understand that your asessee getting income from two sources namely :
1. Salary
2. House property.
If there is no other source of income there ITR 2 return form should be used to file his retrun.
Further you have mentioned that he wants to file the return for the AY 11-12, on this my reply is that time to file the return for AY 11-12 was 30th september 2012 and he could file his retrun latest by 31st March 2013.
Hence time to file the late return has now past.
Further more, you have mentioned that he has tax payable for this AY. On this fact i have confusion since you have mentioned also in your facts that client getting salary and he has also showed his rental income in the form 16. So if he has only these two sources and disclosed his all income to his employer in that case employer himself should deduct all the taxes. please clarify your fact.
Hope above clarify your issue, please let us know in case need further clarity on above.
Thanks
